Question

I need to perform the indicated operations, but when I try to do this, it gets all messed up. Can anyone explain how they go about getting the correct answer for this?

2 2/5 * 3 1/2 - 4/5 = ?

My college mathbook doesn't explain much.

Answer 1

((2 2/5) * (3 1/2)) - (4 / 5) = 7.6

Answer 2

is it correct?

Answer 3

I didn't think it would be a decimal. I assume it would be an even number at the end.

Answer 4

is it 22/5 or 2 2/5?

Answer 5

two and two fifths

Answer 6

ok

Answer 7

7.6 is correct....

Answer 8

I was trying to go about it as 10/5 * 7/2 - 4/5, but I don't know if thats the right way. Thats when you'd find the least common denominator of all three, but i don't seem to be able to find one that isn't overly high.

Answer 9

oh okay :) then i guess i was right. thank you!

Answer 10
